Best CPU Fan smoothing up/down time setting?

Hi@all,

i´m currently looking for some optimizations for my system, a Ryzen 5 1600x based Gaming PC. Fan Setting for CPU and Chassis in in PWD mode.
Not even in peaks (starting steam, an other program or even games), the fan speeds up and mostly down a little later.

What do you thing is the best FAN smooth up/down setting without running in problems? Fans should spin up if needed but as silent as possible...
